No 'credible' security threats to Trump inauguration: government

DULLES: US Homeland Security Secretary Jeh Johnson said Friday the government sees no immediate threats for the January 20 inauguration of President-elect Donald Trump.

Johnson said US authorities have ramped up security preparations in light of the rise of "lone wolf" type attacks, including recent atrocities in France and Germany in which jihadist-inspired attackers drove trucks into large crowds.

But he stressed: "We know of no specific credible threat" to the massive event, addressing reporters at a secure communications facility west of the capital.

He said 700,000-900,000 people are expected for the Washington event, including 99 different protest groups. Some 28,000 security officials will be deployed.
